Why don't elites utilize heart rate as feedback in their training and/or racing?
I note that many top Bikers are seen wearing heart rate monitors both in training and racing. John Tracey and Viren,along with the East Germans were big advocates of heart rate monitoring. One never hears Salazar talk about heart rate
in relation to the training of his athletes.
It is some what surprising that Salazar does not incorporate heart rate monitors
into his arsenal of gadgets. Do any of todays top runners utilize a heart monitor?
